Root Phenotyping of Two Soybean (Glycine max L.) Cultivars in a Vertisol of Central India

Not AvailableThe root system architecture (RSA) is a highly plastic trait and in evitable for plant growth because of its role in water and nutrient acquisition. Soybean, an important economic leguminous crop of India, but its RSA is largely unknown. The RSA of two popular soybean cultivars grown in central India viz., JS-335 and JS-9560 was investigated to compare their root phenotype in a clay soil under laboratory condition. It has been observed that root length, root surface area and root volume of JS-9560 were significantly higher than that of JS-355; whereas root diameter of JS-9560 was significantly lower compared to JS-335. Further, in JS-9560, number of nodes, primary roots, secondary roots, length of primary roots and secondary roots were 17, 8, 20, 24 and 16% higher than JS-335. Primary and secondary root insertion angle was observed to be 33 and 11% narrower in JS-9560 than in JS-335. Based on the findings, JS-9560 showed superior RSA over JS-335 and thus, the cultivar may be consider for further physiological and molecular studies for its adaptability to moisture stress condition.Not Availabl
